3 Claims.

This invention relates to electric light fixtures for a tubular lampbulb, and more particularly to a light fixture for illuminating a chartor display card with ultra-violet light.

The primary object of the invention is to provide an attractive lightfixture which has its essential parts self-contained but readilyaccessible for repair or replacement.

Another object of the invention is to provide an improved method forsecuring a reflector within the fixture so as to reflect the light wavesthrough the angularly disposed glass panel, and at the same time preventlight from shining through openings in the front of the unit.

The invention is illustrated in a preferred embodiment in. theaccompanying drawings, in which- Fig. 1 is a front elevational view of alight fixture embodying the invention; Fig. 2, a top plan view of thesame; Fig. 3, a top plan View, with the cover panel in open position;Fig; 4, a sectional View, taken as indicated at line 4-4 of Fig. 1; andFig. 5, a sectional view, taken as indicated at line 5-5 of Fig. 3.

In the embodiment illustrated, a metal box has a base 6 and anintegrally formed rear wall I to which a top is hinged at 8, and a frontwall 9. The front wall 9 is shorter than the rear wall, so that the topportion of the end walls It] and II which connect them, lies at an angleof about 30 with the base. This angle has been found to achieve the bestillumination of a display card, indicated by dotted lines at l2. Thefront wall has its top edge portion turned rearwardly and inwardly toform a flange it against which the front edge of a reflector I4 ispressed.

Socket members l5 for a lamp it are secured to the end walls, and thesesockets are connected by wires H to a fuse box 18 bolted to the innerfront wall, as indicated at IS. The fuse box is connected to a source ofelectric current by an electric cord 20 which extends through the endwall Ill. The front wall 9 may be also provided with an opening 2| tothe fuse box through which a fuse 22 may be replaced without opening thefixture.

Slots 23 are cut in the front wall, and bracket keepers 24 are pressedoutwardly to slidably receive the legs of brackets 25 which have fingers26 to hold a suitable card l2.

The reflector member i4 is preferably made of thin resilient metal andis concave, so as to fit beneath the tubular light bulb 56. As bestshown in Fig. 5, the front edge of the reflector has a front flange 21,adapted to rest on flange l3 of the front wall of the box. The rear legof the reflector it rests on the back of the box. when in open position,but when pressed to normal position by engagement with the hinged covermember .29 will be forced into the position shown in Fig. 4.

The cover member 29 has an open top frame and downwardly extendingflanges 38, to enclose the top portions of each of the upwardlyextending box walls. A pane of tinted glass M has its edge portionsbound in a rubber molding 32, and the panel is secured in position bymetal clips 33.

The front flange of the cover is provided with a rotatable finger screw34, to engage a tapped opening 35 in the front wall, and hold the coverin the position shown in Fig. 4, by the rubber binding strip engagingthe top of the rear leg 28 of the reflector, and also its front flange21. This makes a very snug fit, so that the parts are held in positionat the proper angle, and will not rattle if subjected to vibration.

The fixture may be used to illuminate a large independently supportedcard which is printed with suitable material so as to glow brightly whensubjected to ultravioletlight. If preferred, a smaller card may bemounted in the fingers 26 of the brackets 25, which are slidably mountedin the keepers 24. Due to the position and tight fit of the reflector,light will not shine through the slots 23 at the keepers.

To open the device, it is merely necessary to remove the finger screw 34and raise the cover.

No tools are required to remove the lamp, and then the reflector may belifted out to permit access to the lower inner portion of the box.

The foregoing detailed description is given for clearness ofunderstanding only, and no unnecessary limitations should be understoodtherefrom, for some modifications will be obvious to those skilled inthe art.

I claim:

1. An ultra-violet light fixture comprising: a metal box having a basewith a rear wall, a shorter front wall with itstop edge portion turnedinwardly and rearwardly, and end walls joining said front and rearwalls; a, resilient downwardly concave reflector having an outwardlydirected flange adapted to rest on the inturned edge of the front wallof said box, and a rear edge adapted to engage the upper portion of saidrear wall of the box, said reflector hav-- ing a length less than thebox and adapted to rest in the box above said base; lamp sockets on saidend walls above the bottom of said reflector; a tubular lamp in saidsockets within said refiector; a fuse box in said box below saidreflector electrically connected to a source of current supply and thelamp sockets; and a metal cover member hinged to said rear-wall andhaving an open top frame and downwardly extending flanges to enclose thetop portions of all of the box walls, a tinted glass panel mounted insaid frame with its marginal portions bound in rubber-like material sothat when the cover member is turned to closed position the binding willengage the rear edge of the reflector and press the front flange of thereflector snugly against said in-turned edge of the front wall and holdthe reflector firmly in position.

2. A light fixture as specified in claim 1, in which the front wall ofthe box is slotted and provided with outwardly extending bracketkeepers, and a pair of card-supporting metal brackets slidably mountedin said keepers.
